If you had done it at thePython level, you would have had a much easier time of both implementingand updating it.As an example, have a look at my osVFS stuff. This is a replacement forthe os module and open() that tricks Python into using a virtual filesystem;http://minkirri.apana.org.au/~abo/projects/osVFS-- Donovan Baarda <abo at minkirri.apana.org.au>
